Chapter 24 In The Crosshairs
TWENTY-FOUR
IN THE CROSSHAIRS
ART
The summons came at dawn.
I hadn't slept. Couldn't sleep. Had spent the night pacing my small room, listening to distant sounds I couldn't identify, wondering if every footstep in the corridor was someone coming to tell me Tom was dead.
He'd gone after Peter. That was the last I'd heard. Ruth had whispered it through my door sometime after midnight, her voice tight with fear. “Tom's pursuing him. Toward the perimeter. Finch has sent guards.”
Then nothing. Hours of nothing. Just silence and darkness and the steady tick of my own heartbeat counting down to something I couldn't name.
When the knock finally came, I was already dressed. Already waiting. Already braced for the worst.
“Mr Pembroke.” A guard I didn't recognise, face professionally blank. “Captain Finch requests your presence. Immediately.”
The walk to Finch's office felt longer than usual. Corridors that I'd memorised over three years suddenly seemed unfamiliar, distorted by exhaustion and fear. People passed me with expressions I couldn't read. Some looked away. Others stared with something like pity.
Ruth was already there when I arrived, standing at attention before Finch's desk. Her face was grey with tiredness, dark circles carved deep under her eyes, but she straightened when she saw me. Relief flickered across her features, quickly suppressed.
“Mr Pembroke.” Finch gestured to the space beside Ruth. “Join us.”
I took my position. Waited. The silence stretched until it became its own kind of torture.
“Lance Corporal Rowe was apprehended last night.” Finch's voice cut through the tension like a blade.
“Attempting to set a signal marker beyond the perimeter.
He's confessed to passing information to enemy intelligence handlers for the past four months.
Including details about this facility's function and location.”
The words landed, but they didn't bring relief. Just a different kind of dread.
“So I was right,” I said. “The estate is the target.”
“You were right about many things, Mr Pembroke. The leak. The source. The pattern of betrayal.” Finch's jaw tightened. “I should have listened sooner.”
Should have. Past tense. The words tasted like ashes.
“And Tom? Sergeant Hale?”
“Alive. Minor injuries from apprehending Rowe. He's been debriefed and returned to duty.” Finch's expression flickered with something that might have been approval. “He caught Rowe cleanly. Got a full confession.”
The relief was so intense it made my knees weak. Alive. Tom was alive. Everything else could wait.
“What happens now?” Ruth asked.
Finch stood, moved to the window, stared out at the snow-covered grounds. His reflection in the glass looked older than the man I'd faced across this desk so many times. Tired in ways that went beyond sleepless nights.
“Rowe claims the bombing run is scheduled within the next twenty-four to forty-eight hours. Possibly sooner.” He turned back to face us.
“Command has decided the intelligence value of this facility outweighs the risk of evacuation.
We're implementing defensive protocols. Hardening what we can. Preparing shelters.”
“So we're staying.” My voice came out flat. “All of us. Right in the target zone.”
“Yes.”
“And if their accuracy is good?”
“Then we accept casualties as part of the cost of maintaining operational capability.” The words sounded rehearsed, like he'd already had this argument with superiors who'd made the decision and left him to enforce it.
“I'm telling you this because you deserve to know what's coming. And because I need you both to continue working.”
Ruth made a sound beside me. Something between a laugh and a sob. “You want us to keep cracking codes while bombers line up to kill us?”
“I want you to do your jobs. Just as I'll do mine.” Finch moved back to his desk, pulled out a folder. “There's one more thing. An intercept that came in overnight. Different cipher variant, possibly containing final targeting details or attack timing.”
He held out a single page. I took it automatically, eyes scanning the encoded text. Letter patterns. Frequency distribution. The familiar puzzle of enemy communications, except this time the puzzle might be the only thing standing between us and annihilation.
“If we can decode it,” Finch continued, “we might be able to anticipate the strike window. Prepare more effectively. Save lives.”
“Or we decode it too late and die knowing exactly what killed us,” Ruth said.
“Also possible.” Finch met her eyes without flinching. “But I'd rather die fighting than die waiting. Wouldn't you?”
Hut X was different when we returned.
The usual sounds were there, typewriters and murmured conversations and the scratch of pencils on paper, but underneath ran a current of tension that made everything sharper.
People worked with the kind of manic focus that came from knowing time was running out.
No one joked. No one complained about the cold or the food or the endless hours.
They just worked, heads bent over intercepts, trying to wring meaning from encrypted chaos.
Peter's desk sat empty. Someone had cleared it already, removed his personal effects, erased all evidence of his presence.
As if he'd never been there at all. As if two years of sitting three desks away from me, sharing complaints about the tea, asking questions about operational outcomes, could be wiped away with a quick tidying.
I settled at my own desk and spread out the new intercept. Stared at it until the letters blurred and reformed into patterns my conscious mind couldn't quite grasp.
Modified cipher. I could see that immediately. The frequency distribution was wrong for standard Enigma, wrong for the Lorenz variants I'd spent three years decoding. Something new. Something designed specifically for communications they couldn't afford to have compromised.
Which meant this message was important. Important enough to warrant special encryption. Important enough to be worth the extra effort.
Important enough, possibly, to contain the details that would save us or confirm our doom.
I started working.
Ruth took the desk beside me, pulling up her own intercepts, cross-referencing with anything that might provide context.
Noor appeared periodically with updates from the wireless room, fragments of traffic that might or might not be related.
The other cryptanalysts worked around us, each lost in their own section of the puzzle, all of us trying to find the thread that would unravel the enemy's plans before those plans unravelled us.
Hours passed. I lost track of how many.
My hand developed a tremor from gripping the pencil too tightly. My leg bounced so hard the desk vibrated, papers shifting with each jolt. Every sound from outside made me flinch, sirens that weren't there, explosions that existed only in my imagination.
Ruth brought me bread at some point. Stood over me until I ate three bites, then returned to her own work without a word. The bread sat heavy in my stomach, threatening rebellion.
Fourteen hundred hours. Something clicked.
The cipher variant was modified Lorenz, but the key generation had been rotated in a pattern I recognised. Fibonacci sequence. The Germans sometimes used mathematical progressions for high-security communications, assuming Allied codebreakers wouldn't think to check such elegant structures.
They'd assumed wrong.
I started applying the logic, watching letters transform into fragments of German that almost made sense. Koordinaten. Coordinates. Zeitfenster. Time window. Best?tigung erforderlich. Confirmation required.
Fifteen hundred hours. More clarity.
Could read whole phrases now. Targeting coordinates that matched the estate's location. Timing windows that narrowed down when the attack would come. Expected results expressed in cold military terminology that reduced human lives to acceptable losses.
My hands were shaking badly now. Had to press them flat against the desk to steady them enough to write.
“Ruth.” My voice came out hoarse. “I'm getting something.”
She was beside me in seconds, reading over my shoulder. Her breath caught as she processed what I'd decoded.
“Two-wave attack,” I said. “First wave marks targets with pathfinder aircraft. Second wave follows to bomb what the pathfinders identify. If we can confuse the pathfinders, make them think they've hit the wrong location...”
“We might survive.”
“We might.”
“How long until the first wave?”
I checked the timing window against my watch. My stomach dropped.
“Hours. Maybe less. The intercept was sent last night. If they're on schedule...”
Sirens.
The sound cut through everything, rising and falling, mechanical scream that transformed theoretical threat into immediate reality. Air raid. Incoming bombers. Attack beginning now.
For one frozen moment, nobody moved. The sound hung in the air like a physical weight, pressing down on all of us, stealing breath and thought and the ability to react.
Then chaos.
People scrambling from desks, grabbing coats, running for exits. Typewriters abandoned mid-word. Papers scattering as bodies collided in the narrow aisles. Voices shouting instructions that nobody could hear over the sirens.
Noor appeared at my shoulder, yanking on my arm. “Art! Move! We have to go!”
“Not yet.” I was still writing, pencil flying across the page, trying to capture everything I'd decoded. “Almost have it. Just need to finish—“
“You'll be dead before you finish!”
“I need five minutes. Maybe less. If I can complete the targeting sequence, Finch can use it to redirect defenses—“
“Five minutes might be all we have!” She was pulling harder now, physically trying to drag me from my chair. “Please. Please, Art. I can't watch you die for stubbornness.”
“Go.” I shook her off, kept writing. “Get to shelter. Get everyone out. I'll follow.”
“Art—“
“Go!”
